List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-96a1-0050c2490048 cobalt-60 The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 73c7ade5-9f51-560f-b6ca-c556588b7735 Cobalt-60 The CAS numbers are the same (10198-40-0); both name the same compartment.
bafu 2026-v1 d286e601-7d9f-53a8-82ab-f417c3cddbe5 Cobalt-60 The CAS numbers are the same (10198-40-0); both name the same compartment.
